I find my phone is my worst enemy in dealing with rejection. It's always so tempting to be in contact with someone when you like them but there's the whole love/hate thing going on. I could never stop myself from texting with possessive intentions and trying to cover it up by trying to be 'just a friend'. It always felt false because I was still seething inside and it was just a subconscious way of trying to get close in order to attack someone and deliver a deathblow. All or nothing, very typically 'I will have the last say' and a very shitty thing to do to someone. I'm not proud of the fact that none of my ex's want to know me. Deleting numbers is the harder path but lets you get on with things without trying to dig up the past.
What I'm saying is, it's said we have an iron will but so many have trouble applying that same iron will to walking away from something that no longer works or is unhealthy. Walking away is a choice and everyone has that choice; I figure any decent native scorp attracts this sort of thing a lot in life (stirring up drama and having your heart ripped out/ripping it out yourself) and most of the time we do it subconsciously...so do it consciously instead. Face it. Feel out of control. If you hate the person, really make an effort to fucking hate them so it's out of your system, then remember why you loved them; I've found this is really helpful in forgiving other people and yourself. You can't control whether other people love you or not but you do have choices about what you do next and how to move on.
